A field guide, not another blog post
Thirteen pages on what Google changed between August 2025 and May 2026, which sites paid for it, and the actions we take because of it — mobile-first indexing, topical relevance, E-E-A-T, and the point where AI stops saving you time and starts costing you rankings.
It is written the way we brief our own clients — plain language, no tool worship, and no tactic we would not run on a brand we are accountable for.

Inside the 13 pages
What’s happening in the SEO industry
The six things search engines are prioritizing right now: mobile-first indexing, the overuse of AI-driven content, user experience, Core Web Vitals, high-quality content and E-A-T — and why machine learning inside the ranking systems changes how each one is judged.
Major changes in search behavior
Mobile-first indexing, topical relevance and AI tooling, each with the action to take. Including how Google compares a page’s embeddings (siteRadius) against your site’s focus (siteFocusScore) to decide how on-topic that page really is.
Every update of the past year, named and dated
Spam (August 2025), Core (December 2025), the first core update ever aimed at the Discover feed (February 2026), a spam enforcement pass that finished in under 24 hours (March 2026) and the broad core update of May 2026 — what each one set out to reward, and what it demoted to get there.
The over-reliance of AI in SEO
Why Google now de-prioritizes sites that use AI as their primary source of content, what that has already cost large publishers in traffic and rankings, and where automation still earns its place.
Quality above all else
E-E-A-T in practice, plus the four numbers behind it: 67% of clicks go to the first five organic results, 60% of consumers feel less positive about a brand whose content was AI-generated, 54% would rather read a human, and 78% of marketers say custom content outperforms generic AI output.
What the penalized sites had in common
Five shared characteristics — thin or duplicate content, poor user experience, a spammy backlink profile, technical debt, and guidelines broken outright — and the four industries taking the most damage: e-commerce, health and medical, news and media, and local services.
Five sites removed from Google entirely
Named domains that lost their indexing outright, and the specific failures — low-quality content, poor user experience, non-compliance with updated guidelines — behind each removal.
The risks, then our approach
Algorithmic and manual penalties, lost organic traffic, damaged credibility and a forced rise in paid spend. Then the method we run instead: white-hat only, transparent, user-centric, data-driven, continuously revised.

Three Actions You Can Take This Week
Fix the mobile version first
Google ranks the mobile version of your site, not the desktop one. Make it fully responsive, fast on a phone, and seamless at every screen size — then use Google’s Mobile-Friendly Test to find what still breaks.
Build topical authority on purpose
Every page is judged against the core topic of your site. Plan content around the areas where you can actually demonstrate expertise, authority and trust, instead of chasing keywords that pull your site off-topic.
Keep AI in a supporting role
Use AI to speed up keyword research and drafting, then let a real writer carry the quality. Sites that made automation their primary content source lost rankings and traffic — and some lost their indexing.
Is This Guide for You?
Worth your email
Read this if…
- You run e-commerce, health, news or local — the four categories the updates hit hardest, including large affiliate sites.
- Your rankings moved in the past year and nobody can tell you which of the five updates did it.
- You are scaling content with AI and want to know where the line is before Google finds it for you.
- You are about to brief an agency or a hire and want to judge the plan you get back against the guidelines it should be following.
Not for everyone
Skip it if…
- You want the black-hat shortcut — bought links, spun content, a trick that survives one quarter and one manual penalty.
- You need paid media to carry this month's number. Organic compounds; it does not rescue a quarter.
- You publish AI output at volume and intend to keep doing it. The guide will only explain why the traffic went.
The last part is our own method — white-hat only, fully transparent. Created by our Head of SEO.

Before You Hand over Your Email
What exactly do I get, and when?
A download link to SEO in 2026: Staying One Step Ahead of an Ever-Changing Industry — 13 pages, PDF — sent to the email address you enter. Nothing is gated behind a phone call, and you do not have to talk to anyone to read it.
Is it actually free?
Yes. No payment, no trial, no card. We write it because the brands that understand organic search make better clients — and better briefs for their in-house teams.
Will you email me every week after this?
Only if you tick the consent box on the form, and you can unsubscribe from any email we send. Leave it unticked and you still get the guide.
How current is it?
This is the 2026 edition. Its update log runs from the August 2025 spam update through the broad core update of May 2026, which was the most recent when the guide was written — and the criteria those updates enforce, mobile-first indexing, topical relevance, E-E-A-T and the penalty for AI-first content, are the ones we work to today.
Can I share it with my team?
Please do. It is written to be forwarded to whoever owns the site, the content and the roadmap — those three people rarely sit together, and the guide is most useful when all three have read the same thing.
Is this a pitch for your agency?
Twelve of the thirteen pages are the industry, the updates and the actions. One page is how we work. If you would rather we ran it for you, the results we have published for other brands are on the case studies page — read that instead of taking a sales call.
